You should have much more than 100 cards in your pool
That opens up all sorts of possibilities, although since its a Stage 2 Pokmon, it still takes a bit of work and quite a lot of space in your deck to get it going
However, it is possible to include cards that are not a part of these setsand that do not have a Regulation Markand still have a deck that is legal in the Standard format
I had hopes for this, but not very high and it failed even what I expected of it
Waterfront Bouncer was an exception to this rule, able to turn all of those bad cards you were forced to play into bounce spells
All you need is a Fabled Passage or an Evolving Wilds in your graveyard, and you'll be able to play it, sacrifice it to find another land, and then put it back into your graveyard all in the same turn, every turn
